All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Recent reports from many parts of the United States indicate that the so-called zinc-deficiency disease is wide spread. It affects some varieties of trees in some areas and all varieties in other areas, and occurs from Florida westward to the Pacific coast and northward to the Canadian line. Although the disease is more prevalent in trees, it is also known to affect annual plants.

Cambrian Stratigraphy In The Northern Wasatch Region, George Burke Maxey
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
An exhaustive field study of the Cambrian stratigraphy of the northern Wasatch region indicates that in addition to the Blacksmith Fork section there are two complete and better exposed middle and upper sections. Several other good exposures of the lower Middle Cambrian section have been studied in detail. The Spence shale is found to be a member low in the Langston, not the basal member of the Ute. Relative ages of the Spence shale and Ptarmigania faunas have been determined. Other Cambrian faunal zones have been discovered and are discussed. Paleontologic evidence suggests that the Nounan formation is of Upper …
